As the spring was taking the place of the winter, the weather was cooler and it was even warm from time to time. The sun was high in the sun and there weren't many clouds in the blue sky. At the Philadelphia Police Department headquarter, Lilly Rush and Scotty Valens were sitting at their desks, doing some paperwork.

They raised their heads, as they heard footsteps coming towards them. "Can we help you?" Lilly asked to the old woman.

"I'd like to reopen the case of my daughter." The woman answered with a sad smile.

"Please, take a seat." Lilly said to her while showing a chair. The woman sat on the chair and put her handbag on her laps.

"What's your daughter's name?" Scotty asked while taking his notebook and a pen.

"Her name was Kathleen Evans, she's 18... She was killed in an alley in the city... that's all I know..." The woman answered, fighting against the tears.

"Her name was Kathleen Evans... She was killed in an alley in the city... that's all I know... The policemen whom inquired into my daughter's case didn't look to care very much about catching the murderer of my daughter..." The woman answered, the eyes filled of tears.

Then she took something out of her bag. "This is Kathleen's diary, I found it in a whole in the wall of Kathleen's old room." She said, handing it to Lilly, who took it and flipped through it. "Somewhere in the diary, she talks about a man of who she's scared."

"Have you an idea of who it could be?" Lilly demanded, continuing to flipped through it.

"No, I really don't know..." The mother answered sadly.

"Okay, we'll se what we can do." Scotty softly said while standing up.

Lilly and Scotty were looking into the box, and Stillman had joined them. "She was raped and stabbed 4 times..." Scotty read aloud, while reading and looking at the picture.

"Any Suspect?" Stillman asked while looking at the photo of Kathleen, she seems so happy on it, with her boyfriend and some friends. Carefree, not knowing what was gonna happen to her.

"Tom Perkins, 30 at this time, he was found prowling in the streets. But they released him from prison because they didn't have enough proofs. And Lydia Evans, Kathleen's sister, she's pretty jealous of her." Lilly answered while reading.

"There was some semen, but they didn't find who it was." Scotty said while closing the file.

"So it's a man... " Lilly concluded while looking at the photo Stillman gave her.

"What about her boyfriend? Maybe he's a bit too possessive?" Scotty proposed while putting back the file and the photo in the box.

"Yeah, maybe. You and Lilly, go and see the sister." Stillman said. And he got out of the room.

Scotty and Lilly were in the car, driving towards Evans' house. "Even in my sleep, I heard him calling me, or I heard his footstep behind me even if he's not." Lilly read aloud with a neutral voice. "Who could it be...?" She asked herself.

Scotty stare at her, listening to her. 'I never notice how beautiful she could be...' Scotty thought, while looking at her.

"Scotty! Look at the road!" Lilly shouted, surprised.

Scotty shoke his head, and looked back at the road. "Sorry, I.. I was just thinking..." He said with an hesitating voice.

'You're stupid Scotty... First, it's your partner, you shouldn't think this! And second Lilly is the ice queen of the headquarter, don't even think about that.' Scotty thought, feeling stupid while looking at the road.

And Scotty parked the car in front of a green house. The plants in front of it were faded as was the grass. It was a sad house, completely neglect by its occupiers. They got out of the car and walked towards the house. When they arrived at the door, they knocked on the door and waited. A tall woman came to open to them, she had dark brown hair like Kathleen's, bright brown eyes and a round face.

"Lydia Evans?" Scotty asked to her and the woman nodded.

"Who are you?" She demanded with a confussed look. She was looking Lilly to Scotty, searching in her head where she could have met them, with their long dark coat and their scarfs, it was strange for the woman. And during an instand she sudeenly changed in a younger Lydian who was about 12.

"Detective Rush and Valens." Lilly answered while flashing her badge. "We'd like to ask you some questions about Kathleen."

"She's dead, isn't she? Why are you coming here with your badges and ask some questions about her like that? Let her where she is and everyone will be alright." She answered offended.

"Because everybody deserved justice." Lilly answered calmly.

"Mind if we come in?" Scotty asked while looking at the hall of the house.

The woman sighed and stepped aside, letting them enter. And she led them towards the living room, where an imposing man was lying on the couch, watching tv. The room was as neglected as the outside of the house.

"Yeah, I know, the house is completely abandonned. My mother was so devastated by the death of my sister that she couldn't clean even a inche of the house. Always going at the cemetery..." She said while rolling her eyes as she saw the look of the two detectives.

"You don't look particularly concerned by the death of your sister, am I wrong?" Lilly asked while sitting on a pouff. And Scotty sit next to her, taking his notebook from his coat and looking at the picture hang on the wall.

"No, no particularly. I hated her since I was born. She always was the favorite daughter, the perfect girl, always first in the class, and so on, my parents were completely abandonning me! I was the black sheep of the familly!" She pratically shouted, remembering her sister.

"So you have a good motive to kill her." Scotty concluded, staring at her.

"You still think I killed her? Oh your unbelievable... She's my sister! Yeah I hated her, but not enough to kill her!" She told them indignant, while frowning.

"And you don't have any alibi, everything is against you." Lilly said with an insistant look.

Then the woman sighed, while looking at the picture. "Maybe I don't have an alibi but I know what I'm talking about. But I think I've saw something that would help you..."

Flash Back in 1998

"What are you doing here?" a female voice said, surprised. It was Kathleen's. Younger Lydia, walked down the dark corridor, towards the hall where stood Kathleen and a very tall man. But it was so dark that Lydia couldn't see the face of the man.

She slowly walked behind the chest of drawers so that the two persons couldn't notice her. She know that she was too curious but couldn't help herself of spying her sister.

"I wanted to see you!" The loud man's voice said, holding out his hand to Kathleen who push it away.

"I don't want to see you anymore! It's over, I've already told you! Stop following me okay?" She shouted at the man. "Now get out of here and leave me alone!" She said, trying to control her nerves.

"But, Kath! I need you! Please..." The man implored her.

But she closed the door in front of him, and leaned against the door, waiting to hear his footstep leaving.

Back in 2005

"Do you have any idea of who it could be?" Scotty asked while noting on his notebook.

The woman shook her head, and Scotty and Lilly looked at each other.

Jeffries and Vera were in a nursery school, waiting for the friend of Kathleen. As they waited they looked at the little kids playing. Then one of them walked towards them and put a toys on Vera's laps.

"Huh... what does he want?" Nick asked to Jeffries, while smiling with a forced smile at the kid.

"He wants to play with you." Will answered amused.

"Haha, that's funny..." Nick said started panicking, not knowing what to do.

"I've already told you, play with him!" Will persisted, wanting to see Vera playing.

Then Nick took the toy and kneeled down next to the boy. The little kid looked at him with an effraid look and started to cry.

"No no no, don't cry, it's okay!" Nick said, trying to reassure the boy.

And he turned to look at Jeffries for help, but he was shaking with laughter. Then a woman came to see the boy and toook him in her arms, daring an evil look at Vera.

"But I didn't do anything!" He pleaded.

The woman went away and he went back to his seat.

"Haha, you think it's funny?" Nick said grumpily.

"Yeah, it was killingly funny!" Will answered while wiping his tears.

Then a woman, who was about 25 came to see them. She had long dark blond hair, and bright blue eyes. During a minute she changed in a younger her but came back at the present her.

"Erina Bradford?" Nick asked while standing up and shaking hands with her.

"I'm detective Jeffries and this is detective Vera." Will said while flashing his badge.

"Yeah, what can I do for you?" She askedd gently, with a polite smile.

"We'd like to ask you some questions about Kathleen Evans." Nick said while taking his notebook.

"Kathleen? It's been a long time..." She said while passing her hand in her hair. "You're finally reopening her case." Her smile had disappeared, but they could easilly guess that she was happy that her bestfriend's case was finally interesting somebody.

"We know that a man was stalking her. Do you know who it could be?" Wil asked to her.

"A stalker? Oh god... My poor little Kathleen... I didn't even know she was stalked." She answered, a tear running down her cheek.

"How was the relation between Kathleen and Joshua?" Nick asked.

"They were very happy. When they were together, they were always smiling, crazy of each other. Even too much somtimes... Josh was pretty jealous and too protector with Kathleen. He was even paranoiac, he sometime saw her somewhere with an other man, whereas she was at the other part of the city." She said sadly.

"But I don't think he killed her, he wouldn't even hurt her." She replied, guessing that they think that he could have he killed her.

"Had she got any ennemies or somebody who could potentially kill her?" Will demanded.

"Ennemies? No, I don't think so, everybody loved her!" She answered surprised.

Nick and Will looked at each other, asking themselves if it was true.

"Okay, thank you." Nick said while turning around and quitting the building with Will.
